Web Performance Optimization

Website performance directly impacts user experience and SEO rankings.

Core Web Vitals

• LCP (Largest Contentful Paint): < 2.5s
• FID (First Input Delay): < 100ms
• CLS (Cumulative Layout Shift): < 0.1

Image Optimization

Use modern formats and responsive images:

<picture>
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Description">
</picture>

Code Splitting

Split your code into smaller chunks:

const component = React.lazy(() => import('./Component'));

Caching Strategies

Implement proper caching headers for static assets.

Monitoring

Use tools like Google PageSpeed Insights and Lighthouse to monitor performance.
